Nickle Metal Hydride packs generally have better runtime than Nicads, and they also get better on the 2nd and 3rd charge in a day. NiCads are much more finicky, you should really only run them once a week for max performance, and have less runtime generally as well. If you can afford the extra couple bucks, go with NiMH packs. The E-Maxx packs just come as a pair of packs for a little less money.

No problem...we're here to help.

#1. NICADs are older rechargable batteries. They were used forever up until about 2000 / 2001 when they were superseded by much newer and better NIMH or Nickel-Metal Hydride batteries.

#2. Since NIMH doesn't retain "memory" and always comes in much higher capacities, they have replaced NICADS for R/C use. They are clearly better.

#3. An E-Maxx battery is a special 7-cell design sold in pairs for a bit less money. Even though they are bigger by one cell compared to regular TC type 6-cell packs...they are the same cells, etc. There is nothing different other than the cell count. So unless you have an E-Maxx stick to the following for your battery needs:

GP3300 6-cell packs
Sanyo3300 / 3600 6-cell packs
IB3600 6-cell packs

And in the future, look out for the new GP3700 packs.


Stick to the above as a simple guidline as to what to buy and you'll be a happy camper.

Thanks for helping out...my next question is... How should I properly break in a NIMH pack so that I can get the most power, runtime, and life out of the packs? I just got 2 packs of GP 3300’s that I have to put together…
Thanks

There's not much about breaking in... it shold be treated just the same was as in normal use.

That is:

Fully charge the pack on a NiMh compatible peak detect charger. The batts. should be around 45-50 degrees, when fully charged. That is nice hand warm - NOT hot.

Race the pack till the car slows down. DONT drive them untill the car cant move (that's a great way to shorten pack life )

If you want to use them a second time that day, let them cool down 1˝-2 hours befor next charge. Or simply store them untill next race day.

Have a nice day.
